In a particular embodiment, the application tier 204 can include a client gateway 250 that communicates data directly to the client-facing tier 202. In this embodiment, the client gateway 250 can be coupled directly to the CFT switch 230. The client gateway 250 can provide user access to the private network 210 and the tiers coupled thereto. In an illustrative embodiment, the set-top box devices 216, 224 can access the IPTV system 200 via the access network 266, using information received from the client gateway 250. User devices can access the client gateway 250 via the access network 266, and the client gateway 250 can allow such devices to access the private network 210 once the devices are authenticated or verified. Similarly, the client gateway 250 can prevent unauthorized devices, such as hacker computers or stolen set-top box devices from accessing the private network 210, by denying access to these devices beyond the access network 266.

For example, when the first representative set-top box device 216 accesses the client-facing tier 202 via the access network 266, the client gateway 250 can verify subscriber information by communicating with the subscriber and system store 248 via the private network 210. Further, the client gateway 250 can verify billing information and status by communicating with the OSS/BSS gateway 244 via the private network 210. In one embodiment, the OSS/BSS gateway 244 can transmit a query via the public network 212 to the OSS/BSS server 264. After the client gateway 250 confirms subscriber and/or billing information, the client gateway 250 can allow the set-top box device 216 to access IPTV content and VOD content at the client-facing tier 202. If the client gateway 250 cannot verify subscriber information for the set-top box device 216, e.g., because it is connected to an unauthorized twisted pair, the client gateway 250 can block transmissions to and from the set-top box device 216 beyond the access network 266.

As indicated in FIG. 2, the acquisition tier 206 includes an acquisition tier (AQT) switch 252 that communicates with the private network 210.

In a particular embodiment, the live acquisition server 254 can transmit content to the AQT switch 252, and the AQT switch 252 can transmit the content to the CFT switch 230 via the private network 210.

In an illustrative embodiment, content can be transmitted to the D-servers 232, where it can be encoded, formatted, stored, replicated, or otherwise manipulated and prepared for communication from the video server(s) 280 to the set-top box devices 216, 224. The CFT switch 230 can receive content from the video server(s) 280 and communicate the content to the CPE 214, 222 via the access network 266. The set-top box devices 216, 224 can receive the content via the CPE 214, 222, and can transmit the content to the television monitors 218, 226. In an illustrative embodiment, video or audio portions of the content can be streamed to the set-top box devices 216, 224.

Further, the AQT switch 252 can be coupled to a video-on-demand importer server 258 that receives and stores television or movie content received at the acquisition tier 206 and communicates the stored content to the VOD server 236 at the client-facing tier 202 via the private network 210. Additionally, at the acquisition tier 206, the video-on-demand (VOD) importer server 258 can receive content from one or more VOD sources outside the IPTV system 200, such as movie studios and programmers of non-live content. The VOD importer server 258 can transmit the VOD content to the AQT switch 252, and the AQT switch 252, in turn, can communicate the material to the CFT switch 230 via the private network 210. The VOD content can be stored at one or more servers, such as the VOD server 236.

When users issue requests for VOD content via the set-top box devices 216, 224, the requests can be transmitted over the access network 266 to the VOD server 236, via the CFT switch 230. Upon receiving such requests, the VOD server 236 can retrieve the requested VOD content and transmit the content to the set-top box devices 216,224 across the access network 266, via the CFT switch 230. The set-top box devices 216, 224 can transmit the VOD content to the television monitors 218, 226. In an illustrative embodiment, video or audio portions of VOD content can be streamed to the set-top box devices 216, 224.

FIG. 2 further illustrates that the operations and management tier 208 can include an operations and management tier (OMT) switch 260 that conducts communication between the operations and management tier 208 and the public network 212. In the embodiment illustrated by FIG. 2, the OMT switch 260 is coupled to a TV2 server 262. Additionally, the OMT switch 260 can be coupled to an OSS/BSS server 264 and to a simple network management protocol (SNMP) monitor 286 that monitors network devices within or coupled to the IPTV system 200. In a particular embodiment, the OMT switch 260 can communicate with the AQT switch 252 via the public network 212. The OSS/BSS server 264 may include a cluster of servers, such as one or more IPTV data collection servers that are operable to request and store operations systems data, such as network device performance data collected from the set-top box devices 216, 224.

In an illustrative embodiment, the live acquisition server 254 can transmit content to the AQT switch 252, and the AQT switch 252, in turn, can transmit the content to the OMT switch 260 via the public network 212. In this embodiment, the OMT switch 260 can transmit the content to the TV2 server 262 for display to users accessing the user interface at the TV2 server 262.

The CPE 340 includes processing logic 342 and memory 344. The memory 344 includes a performance data request module 346 and a performance data delivery module 348. In a particular embodiment, the performance data request module 346 is executable by the processing logic 342 to send a performance data request to the set-top box device 302. The performance data request may automatically be sent to the set-top box device 302 periodically or in response to receiving a request for performance data from a network device, such as an IPTV data collection server. In an illustrative embodiment, the performance data request may be structured in a format that is independent of a format of a set-top box device operations platform. For example, the performance data request may be formatted according to a format associated with a software interface of the set-top box device 302, such as a RPC protocol or a HPNA standard.

In a particular embodiment, the performance data delivery module 348 is executable by the processing logic 342 to forward requested performance data received from the set-top box device 302 to a particular IPTV network device. In an illustrative embodiment, the performance data delivery module 348 is executable by the processing logic 342 to forward the requested performance data to a predetermined IPTV network device, to the IPTV network device that requested the performance data measurements, or any combination thereof.

For ease of explanation, the various modules 318-322 and 346-348 have been described in terms of processor-executable instructions. However, those skilled in the art will appreciate that such modules can be implemented as hardware logic, processor-executable instructions, or any combination thereof.

Referring to FIG. 4 a data structure 400 that may be used to store and provide performance data is illustrated. The data structure 400 is a tree data structure that may be used by a set-top box device to retrieve performance data measurements of the set-top box device, to store performance data measurements of the set-top box device, or any combination thereof. The data structure 400 may represent a part of a larger tree data structure that includes multiple nodes.

The data structure 400 includes a node 402. The node 402 may relate to performance data associated with a buffer that is associated with a particular set-top box device. The node 402 includes two branches, branch 404 and branch 406. The branch 404 may relate to a buffer_not retried counter of the particular set-top box device and the branch 406 may relate to a buffer_large holes counter of the particular set-top box device. The branch 404 may include data elements 408-412. The data elements 408-412 may relate to specific instances of collected performance data that are associated with the buffer_not retried counter. For example, the data element 408 may relate to the buffer_not retried counter value at a first time, the data element 410 may relate to a buffer_not retried counter value at a second time, and the data element 412 may relate to a buffer_not retried counter value at a third time. The branch 406 may include data elements 414-418. The data elements 414-418 may relate to a counter value associated with a buffer_large holes counter taken at a particular time. For example, the data element 414 may relate to a buffer_large holes counter value at a first time, the data element 416 may relate a buffer_large holes counter value at a second time, and the data element 418 may relate to a buffer_large holes counter value at a third time.

In an illustrative embodiment, after receiving a performance data request at a set-top box device from a customer premises equipment unit, the set-top box device may be operable to identify a node of the data structure 400 that relates to performance data associated with the request. For example, a request for performance data measurements related to a set-top box device buffer may be executed via the node 402. The performance data request may also indicate the performance data measurements associated with the node 402 that are to be retrieved. For example, the performance data request may relate to the value of a buffer_not retried counter at a specified time, such as at time 2. Accordingly, the set-top box device is operable to traverse the data structure from the node 402 to the branch 404 and then to the data element 410 to retrieve the requested performance data. The performance data request may also specify that all of the data associated with a particular node, all of the data associated with a particular branch, or any combination thereof, is to be retrieved. To illustrate, the performance data request may relate to retrieving all of the data associated with the branch 404 (i.e. the data associated with the data elements 408-412). In addition, the performance data request may relate to retrieving all of the data associated with the node 402 (i.e. the data associated with the data elements 408-418). Further, the performance data request may relate to retrieving data associated with the node 402 and data associated with an additional node of a larger data structure that includes the data structure 400.

Referring to FIG. 5 a method of providing performance data is illustrated. At block 502, a set-top box device receives a performance data request from customer premises equipment. The performance data request may identify a first performance data measurement that is related to a performance aspect of the set-top box device.

In an illustrative, non-limiting embodiment, the performance data request may be formatted according to a remote procedure call (RPC) protocol. Moving to block 504, a first portion of a data structure may be identified that includes the first performance data measurement. The data structure may also include a second portion that is designated for a second performance data measurement or an alternative performance data measurement that may be available or accessible from the set-top box device. The data structure may be stored at a data storage device area of the set-top box device or at an external unit associated with the set-top box device. In an illustrative embodiment, the data structure may be a tree data structure, where the first portion of the data structure is associated with a first tree node and the second portion of the data structure is associated with a second tree node.

Proceeding to block 508, the first performance data measurement is retrieved from the data storage device associated with the set-top box device based on the first portion of the data structure. At block 508, data associated with the first performance data measurement is sent from the set-top box device to the requesting customer premises equipment. The method terminates at 510.

Referring to FIG. 6, a method of providing performance data is illustrated. At block 602, a performance data request is sent to a set-top box device from customer premises equipment according to a first format that is independent of a second format associated with operating software of the set-top box device. For example, the performance data request may be formatted according to a remote procedure call (RPC) protocol and the operating software may be formatted according to particular Internet Protocol Television (IPTV) software, such as Microsoft® TV IPTV Edition. In addition, the performance data request may identify a predetermined performance data measurement that may be related to a measurable performance aspect associated with operation of the set-top box device. Proceeding to block 604, the customer premises equipment receives data associated with the predetermined performance data measurement from the set-top box device. The data associated with the predetermined performance data measurement may be provided to the customer premises equipment from the set-top box device in real-time or near real-time with respect to sending the performance data request. The method terminates at 606.

Referring to FIG. 7, a method of providing performance data from multiple set-top box devices is disclosed. At block 702, a first performance data request is sent to a first set-top box device from customer premises equipment via a first dedicated measurement data access interface. The first dedicated measurement data access interface is independent of the operating software of the set-top box device. In addition, the first performance data request identifies a first predetermined performance data measurement that relates to a first measurable performance aspect associated with operation of the first set-top box device. Moving to block 704, the customer premises equipment receives first performance data associated with the first predetermined performance data measurement from the first set-top box device.

Proceeding to block 706, the customer premises equipment sends a second performance data request to a second set-top box device via a second dedicated measurement data access interface. The second dedicated measurement data access interface is independent of the operating software of the second set-top box device. Additionally, the second performance data request may identify a second predetermined performance data measurement that relates to a second measurable performance aspect associated with operation of the second set-top box device. At block 708, the customer premises equipment receives second performance data associated with the second predetermined performance data measurement from the second set-top box device. In an illustrative embodiment, the first dedicated measurement data access interface, the second dedicated measurement data access interface, or any combination thereof, is operable according to a remote procedure call (RPC) protocol. In another illustrative embodiment, the first dedicated measurement data access interface, the second dedicated measurement data access interface, or any combination thereof, is operable according to a home phoneline networking alliance (HPNA) standard.

Moving to block 710, the customer premises equipment may be operable to store the first performance data at a network data storage device. Proceeding to block 712, the customer premises equipment may be operable to store the second performance data at the network data storage device. In an illustrative embodiment, the first performance data and the second performance data are stored at the network data storage device. For example, the first performance data, the second performance data, or any combination thereof, may include a group of data measurements, where the group of data measurements relates to a branch of a tree data structure. The method terminates at 714.
